The 2013 BMW 6 Series Gran Coupe is a four-door model. Until now, the 6 Series had been a two-door, with a sweeping hardtop or convertible soft top. This latest entry into the 6 Series line-up adds another pair of doors for what BMW aptly calls 4+1 seating.
The new 2013 BMW 640i Gran Coupe goes on sale in late June 2012. At the New York International Auto Show, BMW announced the 2013 640i Gran Coupe will retail for $76,895, including $895 destination charge. BMW said the new 2013 BMW 650i Gran Coupe priced at $87,395 will follow later this summer along with an all-wheel-drive 2013 BMW 650i xDrive Gran Coupe retailing for $90,395 (all prices include the destination charge).
The four-door 6 Series Gran Coupe measures 197 inches nose-to-tail, a modest 4.4 inches longer than the two-door coupe. Most of the added space is devoted to the rear passengers, good news considering the back seat of the conventional 6 Series coupe is little more than an afterthought. To put things into perspective, the new Gran Coupe is precisely 4 inches longer than the BMW 5 Series sedan. The 6 Series Gran Coupe is 1.3 inches wider and 2.8 inches lower than the 5 Series sedan.
Despite the added inches, the new Gran Coupe looks familiar, with classic BMW kidney-shaped grilles, upswept headlamps and creased hood. Those lamps are xenon, though BMW is offering a new LED option. The Gran Coupe is distinguished by a crisp line running from front fender to taillamps and the rounded roofline brings to mind the Mercedes CLS as much as the BMW 6 Series Coupe. The good news is that BMW designers have avoided the bubble butt that generated so much controversy with the Porsche Panamera.
To get a bit more headroom, BMW came up with a crafty way to scallop the headliner. But while the maker has placed three seatbelts in the rear, you'll likely not want to squeeze three adults in the back seat, which the maker tacitly acknowledges with the 4+1 designation. We prefer to think of it as a four-seater.
BMW promises the 6 Series Gran Coupe will be lavishly equipped. Features will include the BMW ConnectedDrive infotainment system, rearview camera with Surround View, Lane Departure Warning, Night Vision with Pedestrian Warning and new Adaptive front LED headlamps.
BMW retuned its TwinPower Turbo 3.0-liter inline-6, which now makes 315 horsepower and 330 pound-feet of torque, with 0 to 60 times rated at 5.4 seconds, and an electronically limited top speed of 155 mph. Using the European test cycle, BMW claims a city/highway 30.1 mpg, though the U.S. government numbers won't likely be available until this summer.
There will be three versions of the BMW 6 Series Gran Coupe, including the 4.4-liter V8-powered 650i. It's rated at 445 hp (a 45 hp increase), and 480 lb-ft, (up 30). The 650i Gran Coupe will launch from 0 to 60 in 4.6 seconds, the maker claims. As for fuel economy, expect a slight penalty from the 21/31 City/Highway rating of the 640i two-door and the 15/23 mpg for the 650i Coupe.
The third model, the 650i xDrive Gran Coupe will feature the BMW's all-wheel-drive system.
All models will be equipped with an 8-speed automatic transmission.
The BMW 650i and 650i xDrive Gran Coupes will reach the U.S. late summer as 2013 models.
